Calculate a Total in XML
Trying to calculate a total Item weight. I have very little experience in xml and I thought this is what I would need.
<xsl:for-each select="//Order/Item" >
<xsl:variable name="tw" select='$tw + <xsl:value-of select = "/Weight"/>' />
</xsl:for-each>
but it is not valid.
or something like this
<xsl:for-each select="//Order/Item" >
<xsl:variable name="tw" select='$tw + /Weight' />
</xsl:for-each>
<xsl:for-each select="//Order/Item" >
<xsl:variable name="tw" select='$tw + <xsl:value-of select = "/Weight"/>' />
</xsl:for-each>
but it is not valid.
or something like this
<xsl:for-each select="//Order/Item" >
<xsl:variable name="tw" select='$tw + /Weight' />
</xsl:for-each>

Why not use your data table (sql, access etc.) to do the calculation and then return the data set and write xml?
